This listing solves that problem in one place — offering a complete selection of module 1 worm gear wheels (15 to 60 tooth) and paired Type A \/ Type B worm shafts, all machined from 304 stainless steel for corrosion resistance and long service life. Suitable for hobbyists, prototype builders, and small-scale mechanical engineers who need reliable, dimensionally consistent drive components.\u003c\/p\u003e\n    \u003cp\u003eThe worm gear wheels are available in 15, 20, 25, 30, 35, 40, 50, and 60 tooth counts, with bore diameters ranging from 5 mm (0.20 in) to 12 mm (0.47 in). Pitch diameter is 1.000 in (25.4 mm). Worm shafts are offered in Type A and Type B configurations with bore sizes from 6 mm (0.24 in) to 10 mm (0.39 in). All components are module 1 (1 mm\/tooth pitch), ensuring interchangeability within the same module standard.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include low-speed, high-torque actuator drives for robotic arms and pan-tilt mechanisms, self-locking worm drive lifts for DIY CNC z-axis assemblies, and compact gear reduction stages in automated conveyor or indexing systems.
